Singapore's August Southwest Monsoon has produced drier-than-average conditions through mid-month, with reduced cloud cover and lighter winds favoring radiative cooling overnight and supporting minimum temperatures clustered near 25–27°C. Official NEA guidance and ensemble forecasts indicate typical early-morning lows of 25–27°C at the Changi reference station, tempered by high humidity above 80% and urban heat retention that limit further drops. Recent stable sea-surface temperatures and neutral ENSO conditions reinforce this narrow range, while any late-day showers could raise the floor. Traders therefore assign the highest implied probabilities to 26–27°C outcomes, with resolution determined by the official 24-hour minimum reported on August 23.
